Stiff Matrix

How can I keep my Pantech Matrix form?
Okay. So today I get my phone keypad first. The Pantech Matrix. I read the reviews at least a week, just to know what to expect. I heard a lot of slides burst, the spots, the keys to become rigid, and so on. How can I avoid this? Yes, I'll try to find a case for the phone, but there anything else I should do? (If you answer for this, make sure that A. you have seen the phone before you do something with it. AND B. Knowing q_sku Navy Blue & sku3020343 phone thats the direction I received. I'm going to get this far or green and black)
Obviously just trying to avoid
